Researchers at Penn Medicine have discovered a new approach to treat solid cancers using CDH17CAR T cells, which selectively target and eliminate gastrointestinal (GI) solid tumors like gastric, pancreatic, and colorectal cancers in preclinical models. Unlike other immunotherapies, CDH17CAR T cells do not show toxicity to healthy tissues.

The study's findings suggest that the colon is divided into more segments than previously thought and could lead to the development of new treatments.
A team of researchers discovered that chance plays a significant role in the formation of individual gut microbiomes, with genetic, diet, and environmental factors influencing the odds of colonization. The study's findings have major implications for treatments like fecal transplants and probiotics.
A team led by Case Western Reserve University discovered the novel repair properties of Gasdermin B protein, promoting restoration of epithelial layers and effective wound-healing. The findings have significant implications for designing therapeutics to enhance wound repair in various organs.
Researchers at MIT have developed a pill that can deliver RNA to the stomach, potentially making vaccines easier to tolerate and treat gastrointestinal diseases. The capsule is designed to release RNA in the stomach, where it can stimulate an immune response without being degraded by digestive enzymes.
A study by Kennedy Krieger Institute explores how GI problems in children with autism affect their families. Researchers identified four main themes: anxiety, diet, microbiome imbalance, and medication impact. The findings highlight the need for interventions to address poor gut health and its consequences.
A new study found that a specific type of carbohydrate called ‘fodmaps’ can aggravate intestinal problems, but its impact is not as significant as previously believed. IBS symptoms were found to be influenced more by psychological factors and individual differences in metabolism and intestinal flora.
Researchers identified predictive molecular biomarkers for non-response to anti-TNF and anti-integrin therapies in UC. Biomarkers in innate and adaptive immune systems, as well as proteolytic degradation, were found to be predictive of therapy non-response.
A study published in Scientific Reports demonstrates the use of positron emission tomography (PET) imaging to track the elimination of plastic particles from the bodies of mice. The research reveals that most small plastic particles are eliminated within two days, with smaller particles cleared faster than larger ones.
Researchers developed a noninvasive diagnostic imaging tool to measure the levels of bile salt hydrolase in the gastrointestinal tract, predicting clinical status and efficacy of probiotic supplements. The tool also evaluates prebiotics' ability to increase bile salt-hydrolase activity, offering new insights into personalized health care.
The chemical synthesis of trefoil factor peptide TFF1 enables the study of its mechanisms of action and optimization for therapeutic applications. The new method provides novel insights into the protein's interactions with mucins, accelerating wound healing in the gastrointestinal tract.
A study found that US adults with inflammatory bowel disease tend to eat more junk food, such as French fries, cheese, and cookies, which may contribute to their condition. The research also revealed that these foods can increase the risk of inflammatory bowel disease.
New research from Brown University shows how Candida albicans fungus can adapt to different host environments. The study found that patient samples of the fungus frequently lack one copy of a gene that serves as a vital master regulator, allowing cells to switch phenotype and thrive in various environments.
Researchers at Mount Sinai discover that an antimicrobial protein in the gut can prevent graft-versus-host-disease, a common and lethal side effect of bone marrow transplants. The protein, REG3α, may lead to new treatments for inflammatory bowel disease and other GI illnesses.
Researchers have successfully powered small electronic devices in the gastrointestinal tract using mid-field wireless powering, a technique that operates at higher frequencies for more efficient delivery. This breakthrough could transform disease diagnosis and treatment by enabling implantable devices to operate wirelessly.
Researchers developed a sensor that uses Raman spectroscopy to detect molecular markers of IBD in the colon, helping to distinguish between ulcerative colitis and Crohn's disease. The device could provide an objective gold standard for diagnosis and guide personalized treatment approaches.
Researchers design a new type of extended-release pill that can attach to the gastrointestinal tract lining and release its contents slowly. The dual-sided device uses mucoadhesives and omniphobic materials to resist being pulled away by food and liquids.
A study found that severe burns alter bacteria populations dramatically, leading to a decrease in beneficial bacteria and an increase in potentially harmful Enterobacteriaceae. This imbalance may contribute to sepsis and other infectious complications in burn patients.
